5. '0 oil whom it may concern Be it known that 1, Mar: GARBELL, a citizen of the United States, residing at Chiago, in the county of Cool: and State of Illinois, have invented certain new and useful l1 p ovements in Combined Paper Feed and Finger Releasing Mechanism for Type writers, of which the following is a specification.

The invention relates to improvements in that part of a typewriter employed for the insertion feeding, guiding and holding sheets of paper in the proper positions, and it consists in certain peculiarities of the con struction, novel arrangement, combination and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

T he principal object of the invention is to provide simple, durable, convenient and mechanism whereby the paper holding fingers will be automatically released simultaneously with the release of the paper feed by the same instrumentalities and operation.

Another important object is to provide means for automatically locking or holding said fingers in their released positions or away from the platen until it is desired to return the paper feed and fingers to their normal or operative positions.

Other objects and advantages of the in vention will be disclosed in the following description and explanation.

In the accompanying drawings, which serve to illustrate an embodiment of the invention Figure l is a plan view of a portion of the carriage frame of a typewriter showing my improvements mounted thereon and illustrating the platen and paper table or platform shortened for the convenience of illustration.

Fig. 2 is a transverse sectional view taken on line 2-2 of Fig. 1 looking in the direction indicated by the arrows showing the parts of the mechanism in about their normal or operative positions.

struction of the mechanism in their normal or operative positions.

5 is a similar view of like parts showing them in a different position.

Fig. 6 is a detached perspective View of the lever which operates the paper holding means.

Fig. 7 is a detached perspective view of the main or operating lover of the device looking toward the inner surface thereof, and

Fig. 8 is a similar view of said lever looking toward the outer surface thereof.

Like numerals of reference refer to corresponding parts throughout the different views of the drawings.

The numerals 10 and 11 designate portions of the end pieces or plates of the carriage of the machine which plates may be connected together by means of bars or rods 12 in the ordinary or any well known way and have journaled thereon a shaft 13 on which is mounted between the end pieces or plates 10 d 11 a platen 1d and on its outer ends knobs 15 by means of which the platen can be rotated when desired.

The c' iage frame is supported by suitable carriage rail supports 16 which are located beneath said frame at proper distances apart and extended transversely with re spect to the end pieces or plates 10 and 11 and each of said supports is provided on its upper end with a pair of prongs 17 as is clearly shown in Figs. 2 and 3 of the drawings. Between the prongs 17 of each support 1.6 is located race member consisting of a pair of rails 18 and 19 located side by side and angular in cross-section at their upper portions. These rails provide at their upper portion a race or holder for anti-friction balls 20 on which the carriage rails 21 rest which rails are also angular in cross-section as is clearly shown in Figs. 2 and 3 of the drawings. Each of the carriage rails 21 has on its outer portion a laterally extended flange 22 to rest under and engage an inwardly extended and over-hanging flange 23 with which each member 18 of the races is provided.

The carriage rails 21 may be secured to the bars or rods 12 and to the end plates 10 and 11 of the carriage in any suitable or well known way.

By reference to Fig. 1 of the drawings, it will be seen and understood that the end plates or pieces 10 and 11 of the carriage frame are connected together by means of rocker bars 24: and 25 which are by preference angular in cross-section except at their ends which are cylindrical in order to fit in correspondingly shaped openings in the end pieces 10 and 11 to permit of rocking movement of said bars.

At one end of each of said bars a spring 26 having one of its ends secured thereto and its other end secured to the end plate adjacent thereto surrounds the same to no tuate said bars in one direction. {)ne of the end plates or pieces, usually the one at the right of the machine indicated by the numeral 11, is provided with a horizontally extended arm 27 which has on its inner lower portion a horizontally and inwardly extended ledge or member 28 used for a stop for the main or operating lever of the mechanism and also as a finger rest for the operator.

Mounted on the shaft or bar 24: so as to turn therewith is a paper table or platform 29 which is by preference made of sheet metal and substantially S-shaped in crosssection as is shown. This table or platform constitutes a part of the paper feed and extends somewhat above and rearwardly of the bar 4 on which it is mounted and also extends downwardly and forwardly and then upwardly near the platen as will be readily understood by reference to Figs. 2 and 3 of the drawings.

The table 29 is provided in its front lower portion at a suitable distance from each of its ends with a pair of downwardly extended ears 30 which are by preference punched out of the material of which the table is made, thus leaving an opening between the members of each pair of ears for the reception of a portion of a rubber or rubber tired roller 31, one of which is journaled between each of the pairs of cars and extends through the openings in the table a slight distance as to contact with the paper and to hold it against the platen when the parts are in the positions shown in Fig. 2 of the drawings.

Mounted on one end of the 1%)(561 shaft or bar 24 is a main or operating lever 32 which extends forwardly along the inner surface of the end piece 11 and terminates at its free end near the free end of the arm 27. This lever is provided at its inner end by suitably fashioning said end portion, with an angular opening to receive the angular part of the shaft or bar 2- and on its outer surface at said end with a circular opening 34 to receive the cylindrical part or journal at one end of said shaft. The opening 34 of the lever 32 is formed in a downturned flange on said lever, and by this arrangement it is obvious that as the lever 32 is located on the shaft 24; adjacent to the end plate 11 the angular opening of said lever. will prevent the same turning on said snaft while the tircular opening will surround the cylindrical part of said shaft and abut against the end of the angular portion, thus preventing sliding or displacement of the lever on said shaft.

t will be observed in Figs. 7 and 8 that the flange 35 of the lever has at its inner end a shoulder 36 and below said shoulder a cam or inclined edge 57 which construction will position the front portion of the lever at a slight distance the end pics 11 for the reception and operation of the longer arm 38 of a bell crank lever mounted ,L a El. P J? l on the shalt 20 near one Oi its ends, and used for operating the paper holding fingers or means. This bell crank lever is provided in its upper portion with an angular opening 39 to receive the angular part of the rocker shaft 25 near its end' which is join: naled in the end piece 11 of the ca ge frame, and has a shorter arm ell) provided with an inwardly extended ledge or finger rest 41 for tripping said lever when desired.

Mounted on the rocker bar 25, and by preference for longitudinal adji 'nent thereon, is a pair of paper holding lingers l2 which may be of any suitable -l but by preference of flexible material. shown, these fingers are substantially mental in shape and each of them has its free end a pair of outwardly extenee ears or brackets between each pair c which is journaled a rubber or rubber tiree roller ll to press and hold the paper against the platen in the operation of the machine. The ears l3 are by preference punched out of the front portions of the -32 thus providing an opening 45 in each of said through v-rhich portions of said rollers will extend to contact with the paper. or platen.

Th rocker shaft 25, fingers a2, and rollers 44 constitute a form of the paper holding means which 1 have found efficient, but which construction may be varied wi hout departing from the spirit of the invention.

By reference to Figs. a 6 inclusive. will be observed that the longer arm 38 of the lever which operates the rocker bar 25 the paper holding means is provided near its lower end and on its edge with a downwardly inclined projection 4-6 which terminates with an abrupt shoulder 47 to engage the upper surface of the flange of the lever 32 when the paper feed means is released to locl: he paper holding fingers or means in released po ion as is clearly shown in Fig. of the drawi The in- .s. clined or ram face of the part at of the arn 38 of the bell crank l ver is for engagement with the inclined or shapes edge 37 of the flange'35 on the main or operating lever as shown in Figs. 2 and 4c of the drawings for holding the paper feed and the paper holding means in their operative positions as is clearly illustrated in Fig. 2 of the drawings.

From the foregoing, and by reference to the drawings, it will be readily understood and clearly seen, that assuming that the parts are in the positions shown in Figs. 1 and 2 and it is desired to insert paper between the table 29 and the platen 1 the main or operatlng lever 32 can be depressed at its outer end by placing the thumb or finger thereon with pressure, which operation will cause the rocker bar 24: to reel: forwardly at its upper portion against the tension of the springs 26 thereon.

in this movement it is obvious that the paper table 29 will be moved at its lower portion from the platen and as the inclined or cam edge 37 of the flange 35 on the operating lever slidingly contacts with the inclined or cam part 46 of the longer arm 38 of the bell crank lever which operates the paper holding means, said paper holding means or fingers will be moved upwardly from the platen, thus permitting paper to be inserted between the paper feeding means, the paper holding means and platen and properly adjusted, when by removing the pressure from the operating lever 32 the parts will assume their normal or operative positions as shown in Fig. 2 of the drawings, thus clamping the paper against the platen so that it can be moved as required by turning the platen in the proper direction.

The foregoing operation will be performed by continuous pressure on the outer end the main or operating lever, but if it is desired to automatically lock the paper holding means in its released position when the paper feed is in its released position as shown in Fig. 3 of the drawings, all that is necessary is to depress the lever 82 far enough to cause the shoulder 36 of said lever to engage the shoulder or notch 4E7 of the arm 88, on the lever which operates the paper holding fingers, in which positions the parts will be held until the arm 38 of the bell crank lever is released from the main or operating lever, which may be done by applying pressure to the arm 40 of said bell crank lever, which operation it is manifest will disengage the projection 46 from the flange 35 of the main lever and permit the springs 26 to return the parts to their normal positions.

By my improvements it is evident that the paper can be readily and suitably adjusted without danger of producing carbon marks while straightening it and that both hands of the operator will be free to manipulate the paper as desired.

It will be further understood that by means of the mechanism both fingers of the paper holder will be released from the platen at the same time by the same operation, and by means of the same parts and operation that releases the paper feeding means.
